This was an idea that came about when I brought home several glass insulators from work. I was bored and picked them up out of ditches. So today I actually pulled the parts together and went for it. The one thing I didn't have was a power supply. So a quick stop at Goodwill produced one for $1. You can't beat that. Here are a couple pictures of the finished project.

I used 3 superbright LEDs and tried to keep this a cheap and simple as possible. I was really curious just how simple you could keep making something like this. So here is the build really quick. If you want the really long winded one check my blog here.

So I really just used the insulator, 3 LEDs, 3 resistors, a power supply , a weird electric connector thing , some screw connectors and some electrical tape. After figuring out the LEDs and power supply I was going to use I found on online calculator here. That will tell you what size of resistor to use and how to arrange the LEDs (ie in series/parallel). You should get something like this....

So to the actual build. Cut the connector off the end of the power supply cord and strip the wires. Here is the one part that might throw people for a loop if they aren't used to working with electronics. You need to find out which of the wires is the positive and which is the negative. I used a multi-meter to find mine. If you don't have the ability to check yours find a friend who does and make sure you mark which is which.

Now that you know your positive and negative wires, time to get the rest of the assembly together. I put the resistors on the LEDs next...

Then I started building the weird little clippy thing. I used this because I had it laying around. There really wasn't any reason I couldn't have just used electrical tape for this part as well. This will have the positive current running into it.

Then plug the positive side of the LEDs into the clippy thing.

Hook the negative side up and hopefully you have light....

I used another screw connector to hold the negative wire and the 3 resistors together. Then insert parts.

I just taped them in place and done!

So, that's my cute little light. You can see all my build pics here and blog post about it here. Thanks for looking!
